History

Johnny Williams was a firefighter, until he got transformed into a seventh Clayface by an explosion in a chemical plant. He discovers this mutation after he accidentally killed a prostitute. He wants to commit suicide before he meets Riddler and Hush. They "promised" him a cure for his condition if he helps them. As the seventh Clayface, Williams pretends to be Tommy Elliot so he could confuse Batman. However, when Williams realizes that the two villains are manipulating him, he offers his assistance to Batman in exchange for his family's safety. But, without access to samples for a particular strain of Clayface genetics, Batman cannot cure him. While his mutated cells overtook Williams' normal ones, he died in the woods near Arkham Asylum.

After he became the seventh Clayface, Williams now has a malleable clay-like body that allows him to change size, shape, and density into any form he desires. He also possesses superhuman strength, stamina, and durability, as well as vast regenerative capabilities.
